/ BOTTLE.

SPECIFICATION forming part of Letters Patent No. 529,821, dated November 27, 1894.

Application filed March 12, 1894. Serial No. 503,384- (N'o model.)

To all whom it may concern.-

Be it known that I,;WILLIAM VoN BOKERN, a citizen of the United States of America, residing at Denver, in the county of Arapahoe and State of Colorado, have invented certain new and useful Improvements'in Bottles; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the figures of reference marked thereon, which form a part of this specification. Y

My invention relates to improvements in. bottles, and the object of the improvement is to provide abottle which when once emptied, cannot be refilled; and to this end, my improved bottle consists of the features hereinafter described and claimed, all of which will be fully understood by reference to the accompanying drawings, in which is illustrated an embodiment thereof.

In the drawings, Figure 1 is a longitudinal section taken through the detachable nozzle and neck of the bottle on the line -00, Figs. 3 and 4, the Valve being shown in elevation. Fig. 2 is a side elevation of the neck and detachable nozzle, the connecting sleeve being shown in place. Fig. 3 is a section taken on the line y--y, Fig. 1. Fig. 4 is a section taken on the line zz, Fig. 1,1ooking upward. Fig. 5 is a section taken on the line :r-:r, Fig. 3.

' Fig. 6 is a detail view of a modifiedform of valve.

Similar referencecharacters indicate corresponding parts in these views.

Let the numeral 5 designate the neck of the bottle provided with the integral seat 5 for the valve 6, and shouldered around said seat to support the packing ring 7, preferably composed of cork. The valve is composed of the enlarged head 6, the bulb-shaped lower extremity 6, and the elongated neck 6 connecting the two extremities. .The lower part 6 is preferably made as large as is consistent with its passing through the aperture surrounded by the valve-seat; in other words, the lower part of the valve is made quite heavy to the end that it may retain its seat securely when the bottle isin an upright poprovided with an integral depending safetycap 8 adapted to engage the top of the valveseat when the nozzle is in place. The cap is pressed integral with the lower part of the nozzle, and recessed or hollowed out as shown at 8 on its lower surface to receive the upper part of the valve, the cavity being large enough to allow the valve to move away from its seat to permit the liquid to escape when the bottle is suitably tipped or inverted. Around the concavity 8, the cap is provided with recesses or apertures 8 which afiord an escape for the liquid between the cap and the seat when the bottle is tipped, and the valve unseated. 1

Between the cap and the lower part of the nozzle there is a space 8 surrounding the cap. From this space, lead small orifices 8 which are formed or punched by the mold or matrix around the top of the cap to .afford a passage from the space 8 to the upper part of the the nozzle are solid as shown in Fig. 3. In

assembling the parts of the bottle, the valve is first placed in position, and the cork washer or packing ring 7 placed around the seat. The lower edge of the nozzle is then placed upon the washer, after which the nozzle is IOO cap, a passage way from the opening in the neck to said space, and another passage way from said space to the space in the nozzle above the cap, and suitable means for connecting the neck and nozzle, substantially as described.

In testimony whereof I affix my signature in.

the presence of two witnesses.
